Subject [jira] Updated: (DERBY-1417) Add new, lengthless overloads to the streaming api
Date Tue, 01 Aug 2006 14:49:17 GMT
     [ http://issues.apache.org/jira/browse/DERBY-1417?page=all ]

Kristian Waagan updated DERBY-1417:
-----------------------------------

    Attachment: derby-1417-7a-clientborderfix.diff
                derby-1417-7a-clientborderfix.stat

'derby-1417-7a-clientborderfix.diff' fixes bugs in the client-side implementation. The bugs
caused Derby to hang if the size of the data was the same as the internal buffer, and there
was also a bug that could cause an ArrayIndexOutOfBoundException.

Comments:
1) I have added more tests for ByteArrayCombinerStream, and also done some whitespace changes
here.
2) Added comments to ByteArrayCombinerStream.
3) Made ByteArrayCombinerStream throw IllegalArgumentException for negative lengths and if
there is not enough data for the length specified (detected in constructor). As this is an
internal class, I hope this is acceptable. If not, I would like to know how these exeptional
situations should be handled.

I ran tests with Blob sizes of 1K, 32K, 65K, 10M, 100M and 2G with the client. Tests for 100M
and 2G fails badly, and Derby hangs due to an OutOfMemoryError on the server. The situation
is somewhat improved by the patch 'DERBY-1559.diff', but I still get ugly crashes, like broken
communications pipe. I have not looked these problems.

I ran the jdbc40 suite without failures. I will add more tests soon, but need to coordinate
with other work (might add tests one of the several existing tests).

The patch is ready for review/commit.

Thanks,

> The JDBC4 Expert Group has approved a new set of overloads for the streaming methods.
These overloads do not take a length argument. Here are the new overloads:
> PreparedStatement.setAsciiStream(int parameterIndex, java.io.InputStream x)
> PreparedStatement.setBinaryStream(int parameterIndex, java.io.InputStream x)
> PreparedStatement.setCharacterStream(int parameterIndex, java.io.Reader reader)
> PreparedStatement.setNCharacterStream(int parameterIndex, java.io.Reader reader)
> PreparedStatement.setBlob(int parameterIndex, java.io.InputStream inputStream)
> PreparedStatement.setClob(int parameterIndex, java.io.Reader reader)
> PreparedStatement.setNClob(int parameterIndex, java.io.Reader reader)
> CallableStatement.setAsciiStream(java.lang.String parameterName, java.io.InputStream
x)
> CallableStatement.setBinaryStream(java.lang.String parameterName, java.io.InputStream
x)
> CallableStatement.setCharacterStream(java.lang.String parameterName, java.io.Reader reader)
> CallableStatement.setNCharacterStream(java.lang.String parameterName, java.io.Reader
reader)
> CallableStatement.setBlob(java.lang.String parameterName, java.io.InputStream inputStream)
> CallableStatement.setClob(java.lang.String parameterName, java.io.Reader reader)
> CallableStatement.setNClob(java.lang.String parameterName, java.io.Reader reader)
> ResultSet.updateAsciiStream(int columnIndex, java.io.InputStream x)
> ResultSet.updateAsciiStream(java.lang.String columnLabel, java.io.InputStream x)
> ResultSet.updateBinaryStream(int columnIndex, java.io.InputStream x)
> ResultSet.updateBinaryStream(java.lang.String columnLabel, java.io.InputStream x, int
length)
> ResultSet.updateCharacterStream(int columnIndex, java.io.Reader x)
> ResultSet.updateCharacterStream(java.lang.String columnLabel, java.io.Reader x)
> ResultSet.updateNCharacterStream(int columnIndex, java.io.Reader x)
> ResultSet.updateNCharacterStream(java.lang.String columnLabel, java.io.Reader x)  
> ResultSet.updateBlob(int columnIndex, java.io.InputStream inputStream)
> ResultSet.updateBlob(java.lang.String columnLabel, java.io.InputStream inputStream)
> ResultSet.updateClob(int columnIndex, java.io.Reader reader)
> ResultSet.updateClob(java.lang.String columnLabel, java.io.Reader reader)
> ResultSet.updateNClob(int columnIndex, java.io.Reader reader)
> ResultSet.updateNClob(java.lang.String columnLabel, java.io.Reader reader)
> We should add these new overloads soon so that the build will not break when this methods
turn up in a published Mustang build.
